IMPROVEMENT lN CARPET-FASTENERS.

Specification forming part of Letters Patent No. 181,149, dated August15, 1876; application filed i March 9, 1876.

To all whom it may concern Be it known that I, U. S. DIEEEENBAGEER ofJersey Shore, Lycoming county, Pennsylvania, have invented certain newand usef'ul Improvements relating to Carpet-Fasteners, of whichthefollowing is a specification:

I have devised novel means whereby a carpet may be efficiently held in astrained or stretched condition, not only at a few points, but at pointsas closely together as may be desired, and in a manner practicallycont-inuous, while at the same time it may be taken up and put downagain with little trouble or loss of time.

When my invention is fully carried out, a bead is presented along theedge of the carpet, which may be made effective as a decoration, as willbe hereinafter more fully described and definitely claimed.

The accompanying drawings form a part of this specification, andrepresent what I consider the best means of carrying out the invention.

Figure l is a face view of the fastening means, with a section throughthe carpet. Fig. 2 is a vertical section on the line S S in Fig. 1. Fig.3 is a horizontal section on the line T T. Fig. 4 is a face view of oneof the parts which are permanently fixed at short intervals on thevertical walls or base-board near the floor. Fig. 5 represents the partson a smaller scale. Fig. 1a shows the end of my bars, to which thecarpet is attached.

Similar letters of reference indicate like parts in all the gures.

A is the floor 5 A', the base-board, and B B pieces of hard wood ormetalv permanently fixed to the latter at regular intervals by means ofslight projections B', which-are inindicated by D1. Thedower portion isswelled to form a handsome bead, as indicated by D2. The extreme loweredge of the part D2 is furnished with sharp teeth, (indicated by D3,)

adapted to engage with, and strongly hold, a

carpet, M, by engaging the teeth therewith, just a little within theedge, as shown in Fig. 2. There may be a considerable thickening orbinding upon the edge of the carpet, which will be accommodated withinthe bead or swell D2.

The beaded part D2 is longer than the plain part D1. AAt the junction ofthese parts is a recess, as indicated by d; and the extended portion ofD2 is indicated by d.

Theparts B are first firmly secured upon the wall. Then the parts D areengaged with the edge of the carpet, either all together or one at atime, and the edge of the carpet being forced out to the wall by the aidof an ordinary carpetstretcher or other suitable means, the piece D,having the carpet engaged therewith, is slid into the space between twoof the uprights B, so that the ends of the plane parts D1 are receivedand held in the rabbets referred to.

The notches or spaces d (see Fig. la) each receive one of the strongoverhanging edges of the part B, and make a close fit therewith., whilethe superior length of the beaded parts D2 (shown by d') causes them toabut together in front of the bottom of the part B, and form acontinuous bead. The head of the screw C, which holds the part B to thewall and takes the strain due to the contractile force of the carpet, isconcealed by the abutting together of the extensions d' of the beadedparts D2 in front of it.

There being no strain tendin g to lift the carpet, but only to shrinkit, or draw its edges away from the wall, I can leave the piece Dentirely undefended against a lifting force. When, in case of fire, orfor any other reason, it is desired to take up the carpet rapidly, theseveral pieces D may be slid bodily upward and the carpet releasedinstantly.

Ipropose to form the piece D of strong sheet metal, properly shaped bydies, or otherwise, using iron or hard brass variously surfaced ordecorated. I estimate one-sixteenth of an inch thick, and about one andthree-fourths of an inch in width. The teeth D3 on the lower edge of thebeaded part D2 may be about onefourth of an inch long, and preferablyabout two inches apart.

The bead D2 not only forms a receptacle to receive the binding of thecarpet and any small surplus within the binding which may remain to hethere stowed, but also presents the hooks D? in the right position,without much bending or weakening the metal at the roots of the teeth.Nickel-plated, or otherwise brightly finished, this bead will produce ahighly decorative effect.

I propose for general purposes vto make the pieces D about two feet inlength, and to lo cate the pieces B at a corresponding distance apart;but so long as these dimensions correspond they may be suitably varied.

I claim as my invention- 1. The uprights B and movable slides D D2 d',the latter adapted to engage with the former, and also with the carpetM, and to operate therewith, as and for the purposes herein specified.

2. The beaded parts or slides D, uprights
